Given the sum of facts, poor vacation planning is a fair interpretation of the final story. There's a general absence of hostility towards the US in this story and instead a sense of attraction and willingness to spend vacation time and money here.

We should be directing the treatment of such minor offenses through polished administrative pathways and not 10 days in prison. That person will likely not come back ever again, and it's a shame because there's every indication that this woman would be a fine visitor and customer to local businesses, US and Canadian.

They're just here for pure sightseeing under the most amicable of moods. 10 days in prison.
